【中文标题】为谷歌存储桶创建签名 URL 的问题

【英文标题】：Issue creating Signed URL for google storage bucket

【发布时间】：2021-11-27 15:18:46

【问题描述】：

我正在尝试创建一个签名 URL 并将其运行到缺少库 pyopenssl 问题。我的命令如下：

gsutil signurl -d 10d -u /Users/dineshc/Development/my_key.json gs://console.cloud.google.com/storage/browser/my_data

我收到以下错误：

CommandException：signurl 命令需要 pyopenssl 库（尝试 pip install pyopenssl 或 easy_install pyopenssl）

我的操作系统配置如下：

uname      :    Darwin
ProductName:    macOS
ProductVersion: 11.4
BuildVersion:   20F71


I have python3.7 installed & I created symbolic link: 

ln -s /usr/local/bin/python3.7 /usr/local/bin/python

我的问题：出于某种原因（我认为）gsutil 仍然指的是 python2.5，这是 MacOS 附带的版本并且没有安装 pip。知道如何让 gsutil 使用最新版本的 python 和后续库吗？

【参考方案1】：

您可以运行gsutil -D version 并获得许多有用的调试信息，包括您的 gsutil 安装、用于运行它的 Python 版本、正在加载的配置文件等。

如果您正在运行 gsutil 的 gcloud 安装，您应该会在输出中看到如下所示的一行：

gsutil path: <path-to-google-cloud-sdk>/bin/gsutil

在这种情况下，您应该能够使用 CLOUDSDK_GSUTIL_PYTHON 环境变量 as mentioned in these docs 指定首选 Python 解释器的路径。

但是，如果您正在运行独立安装 gsutil（不是 gcloud 安装的一部分），则应确保通过命令 /usr/bin/env python 启动的 Python 版本是正确的版本——这将是第一个 Python 二进制文件可从您的 PATH 环境变量中指定的目录中发现，因此您可能需要适当地编辑和 export 您的 PATH。
